Royals are not like the rest of us.

There are certain trends and styles that, while not expressly forbidden, are frowned upon.

Royals are held to higher standards and a level of decorum that dictate every aspect of their lives.

“There’s no actual protocol about dark nail polish,” royal correspondent Omid Scobie toldHarper’s Bazaar.

“It’s simply about being appropriate.”

So, why has it always been assumed that there was a ban on bold nails?

“It’s a super-classic, clean look that looks timeless and royal appropriate.”

“Kate leans into this stuff much more than Meghan did.”

“She looked great.”

Why all the fuss, you ask?

Well, it is assumed that royals are forbidden from showing shoulders or cleavage, especially at official events.

Butthe truth about the royal family dress codeis that this is not the case.

The answer is no, mini skirts are not forbidden.

Once again, it comes down to propriety and protocol.

“Royal ladies are expected to wear knee length or longer.”

She is also not the first royal to show off her gorgeous gams via a peek-a-boo design.

“She was always supposed to look her part, but things are way more casual now.”

“What you see is a fully grown, mature man ready to wear the crown.”

Whatever the reason for Prince William’s whiskers, there is no rule that expressly forbids them.

Again, it is a matter of propriety.

And, apparently, Princess Charlotte agrees.

That’s why you will never see a little boy in long pants.

For instance, Catherine, Princess of Wales often uses hers to avoid unwanted contact.

Hence, they often sport bold, bright colors like those favored by the late Queen Elizabeth II.

Black, while elegant and modern, is typically reserved for funerals.

However, that doesn’t mean that the royals are forbidden from wearing it anywhere else.

“Princess Diana had her own dress code,” royal expert Richard Fitzwilliams told Reader’s Digest.

It was seen as a rebellious act."

The truth is, that, while not forbidden, it is a little complicated.

Typically, a royal does not receive her first tiara until her wedding day.

But, like many royal rites of passage, there are exceptions.

So why were tiaras thought to be forbidden before marriage?

“For the gentleman it was a clear sign not to make advances toward the lady in question.”
